【摘要】：改革開放30多年來,沈陽城鄉(xiāng)快速發(fā)展,但農(nóng)村地區(qū)發(fā)展速度明顯比城市地區(qū)慢,中心城區(qū)擴張速度快,造成土地利用的效率降低,“半城鎮(zhèn)化”、“農(nóng)村空心化”等問題日益凸顯,因此,沈陽城市和農(nóng)村土地利用結(jié)構(gòu)和布局的優(yōu)化研究對于地區(qū)城鄉(xiāng)建設(shè)協(xié)調(diào)發(fā)展具有重要指導(dǎo)意義。本文以沈陽市為研究對象,利用定性與定量分析方法、GIS空間分析方法等相關(guān)的分析方法,通過研究沈陽市1986-2016年城鄉(xiāng)建設(shè)用地結(jié)構(gòu)和布局,為沈陽市經(jīng)濟社會快速發(fā)展提供科學(xué)建議和政策保障。論文的主要內(nèi)容包括:1986-2000年,城鄉(xiāng)建設(shè)用地增加169.78 km2,其中城市、鄉(xiāng)村建設(shè)用地分別占28%、72%;2000-2016年,城鄉(xiāng)建設(shè)用地增加151.63 km2,其中城市、鄉(xiāng)村建設(shè)用地分別占71%、29%,呈現(xiàn)出顯著的階段差異性;對沈陽市城市擴張?zhí)卣鬟M行研究分析。運用GIS空間分析中的緩沖區(qū)分析和空間方位分析等方法。得出蘇家屯區(qū)、于洪區(qū)、東陵區(qū)和沈北新區(qū)分別在1986年到2000年和2000年到2016年間城市和農(nóng)村居民點用地擴展的速度和區(qū)域性差異顯著;自城市中心向外圍,城鄉(xiāng)用地擴張強度指數(shù)先增加后降低,約在12 km處呈現(xiàn)峰值;1986-2016年,沈陽市人口城鎮(zhèn)化與土地城鎮(zhèn)化經(jīng)歷了嚴重失調(diào)—重度失調(diào)—嚴重失調(diào)—極度失調(diào)—輕度失調(diào)的過程,這說明沈陽市人口城鎮(zhèn)化與土地城鎮(zhèn)化一直處于波動狀態(tài),雖然從2010年后的離差系數(shù)看,失調(diào)程度有所下降,但是沈陽市人口城鎮(zhèn)化與土地城鎮(zhèn)化失調(diào)情況還是非常嚴重的;沈陽市城鄉(xiāng)建設(shè)用地系統(tǒng)的協(xié)調(diào)度整體水平比較低,至2016年協(xié)調(diào)度整體水平仍然比較低。深入分析后的結(jié)果顯示:在很大程度上,通過城鄉(xiāng)建設(shè)用地協(xié)調(diào)發(fā)展帶來的城鎮(zhèn)建設(shè)用地增加所伴隨的農(nóng)村居民點用地減少的土地面積極少。
[Abstract]:Over the past 30 years of reform and opening up, Shenyang has developed rapidly in urban and rural areas, but the development of rural areas is obviously slower than that of urban areas, and the expansion rate of central urban areas is faster, resulting in a decrease in the efficiency of land use, "semi-urbanization" and "hollowing out in rural areas" and so on. Therefore, the optimization of urban and rural land use structure and layout in Shenyang is of great significance to the coordinated development of urban and rural areas. By using the qualitative and quantitative analysis method and GIS spatial analysis method, this paper studies the structure and layout of urban and rural construction land in Shenyang from 1986 to 2016. The main contents of this paper include: from 1986 to 2000, the number of urban and rural construction land increased by 169.78 km ~ 2, among which urban and rural construction land accounted for 28% from 2000 to 2016. Urban and rural construction land increased by 151.63 km ~ (2), among which urban and rural construction land accounted for 71 / 29 respectively, showing significant stage difference; The characteristics of urban expansion in Shenyang are studied and analyzed. By using the methods of buffer analysis and spatial azimuth analysis in GIS spatial analysis, it is concluded that Sujiatun district, flood area, etc. From 1986 to 2000 and 2000 to 2016, the speed and regional difference of urban and rural residential land expansion in Dongling District and Shenbei New District were significant, and the intensity index of urban and rural land expansion first increased and then decreased from the urban center to the periphery. During the period 1986-2016, the population urbanization and land urbanization in Shenyang experienced a process of serious maladjustment, severe maladjustment, severe maladjustment, extreme maladjustment and slight maladjustment. This shows that population urbanization and land urbanization in Shenyang has been in a state of fluctuation, although the deviation coefficient after 2010, the degree of imbalance has decreased, but the imbalance between population urbanization and land urbanization in Shenyang is still very serious; The overall level of coordination of urban and rural construction land system in Shenyang is relatively low, and by 2016, the overall level of coordination degree is still relatively low. The results of in-depth analysis show that: to a large extent, Through the coordinated development of urban and rural construction land, the increase of urban construction land is accompanied by the decrease of rural residential land area.
